Juan Carlos Díaz Vélez is a data scientist at the Wisconsin IceCube Particle Astrophysics Center (WIPAC) at the University of Wisconsin-Madison.

He is the data products coordinator for the IceCube collaboration, overseeing the processing of experimental data and simulation production. In addition to IceCube, Juan Carlos is also a member and co-coordinator of the cosmic-ray working group for the High Altitude Water Cherenkov (HAWC) Gamma-ray Observatory in Mexico, and a member of the Southern Wide-field Gamma-ray Observatory (SWGO) in South America.

Juan Carlos earned his PhD in physics from Universidad de Guadalajara, in Jalisco, Mexico and his B.S. from Boise State University. He also holds a M. S. in Computer Science. His area of study focuses on astrophysics and the study of cosmic ray measurements, as well as distributed computing.

At Boise State, he studied theoretical models for low-dimensional electron-hole systems, rapidly-rotating Bose-Einstein condensates (BEC), and quantum-dot cellular automata (QDCA). Juan Carlos' research interest include cosmic rays including cosmic-ray anisotropy, parallel computation, distributed and grid-computing, and numerical simulations.
